Cold Hands, Warm Heart

When someone is described as “chilly,” we understand it means “unfriendly” and not that they should put on a sweater. But using low temperature to capture social remoteness is more than just a convention of language. According to a number of studies, there may be a psychological reason for connecting temperature and social relationships.

In a 2008 study, when volunteers were asked to think about a time they felt socially rejected, they described the temperature in the room as being significantly colder than did volunteers who recalled an experience in which they felt socially included, even though the room temperature was actually the same for both groups. In a separate experiment, volunteers played an online version of a ball-tossing game with three other opponents (unbeknownst to the volunteers, they were the sole participants — a computer program controlled the throws). The game was rigged in a way that some of the volunteers never had the ball tossed to them while other volunteers were able to actively participate in the game. After the game, the volunteers were asked to rate the desirability of various foods and beverages. The volunteers who never had a turn in the ball-tossing game (that is, they were excluded) tended to desire soups and hot coffee more than did the volunteers who played a lot in the game.
